Geometry and trig proofs, with diagrams
I was messing with the triangle on the interactive thing, and made the triangle just a line. It said the line is an obtuse isosceles triangle. Really? Is "obtuse isosceles triangle" really another way to say "a line"?
Edit: I was thinking about this and I think the definition of triangle should be (if it's not already) a shape with 3 angles, each greater than 0.
